US officials ask AT&T, Verizon to delay 5G wireless over aviation safety concerns

US Transportation Secretary Pete Buttigieg and the head of the Federal Aviation Administration (FAA) on Friday asked AT&T and Verizon Communications to delay the planned Jan. 5 introduction of new 5G wireless service over aviation safety concerns.

In a letter Friday seen by Reuters, Buttigieg and FAA Administrator Steve Dickson asked AT&T Chief Executive John Stankey and Verizon Chief Executive Hans Vestberg for a delay of no more than two weeks as part of a “proposal as a near-term solution for advancing the co-existence of 5G deployment in the C-Band and safe flight operations.”

The aviation industry and FAA have raised concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters that could disrupt flights.

“We ask that your companies continue to pause introducing commercial C-Band service for an additional short period of no more than two weeks beyond the currently scheduled deployment date of January 5,” the letter says.

Verizon and AT&T both said they received the letter and were reviewing it. Earlier Friday the two companies accused the aerospace industry of seeking to hold C-Band spectrum deployment “hostage until the wireless industry agrees to cover the costs of upgrading any obsolete altimeters.”
